Title: Method for the dihydroxylation of olefins using transition-metal catalysts
Inventor: BELLER MATTHIAS
IPC: C07C35/14
Filed: 2000-04-18
Abstract: The invention relates to a method for the dihydroxylation of olefins using transition-metal catalysts for producing monofunctional, bifunctional and/or polyfunctional 1,2 diols of the formula (I): R1R2C(OH)-C(OH)R3R4. According to the inventive method, olefins are reacted with molecular oxygen in the presence of an osmium, ruthenium and manganese compound or a mixture thereof in water, or in a solvent mixture which contains water, at a pH value of between 7.5 and 13. The catalyst is activated by the addition of an amine, in order to improve the selectivity of the dihydroxylation reaction. The resulting diols are used as solvents, as starting materials for polyesters and other polymers, as intermediate products for agrochemicals, cosmetics or detergents, or in the form of their esters as synthetic lubricants and emollients. The method can be carried out simply and with a high degree of selectivity and is advantageous from an economical and ecological standpoint.

Patent CA-2388531-A1 (CA)
Title: Dual chamber liquid pump
Inventor: STUTZ WILLIAM A
IPC: F04F1/06
Filed: 2001-08-22
Abstract: The fluid pump of the present invention includes an upper enclosure for holding fluid (typically a liquid) from a fluid input source, and a lower enclosure for outputting the fluid to an output line. A first valve (a) controls the fluid input flow into the upper enclosure. A second valve (b) is engaged in a line between the upper enclosure and the lower enclosure to control the fluid flow from the upper enclosure to the lower enclosure. A second fluid input line is engaged to the lower enclosure to input a second fluid (typically a pressurized gas) into the lower enclosure, and a third valve (d) is engaged in a line between the lower enclosure and upper enclosure to control the flow of the second fluid into the second enclosure. A fourth valve (c) is engaged in a fluid output line to control the flow of the second fluid out of the upper enclosure. In the preferred embodiments, each of valves a, b, c and d is controlled by an automated pump system controller. Various embodiments of the present invention include further valves and check valves to provide improved control in the system. The preferred embodiment of the dual chamber pump operates by outputting the liquid from the lower enclosure under a constant, controlled gas pressure.  When the liquid level in the lower enclosure is low, the lower enclosure is filled with liquid from the upper enclosure. To accomplish this, the upper enclosure is pressurized to the same pressure as the lower enclosure, and because the upper enclosure is disposed above the enclosure, the gravitational head causes the liquid in the upper enclosure to flow into the lower enclosure. The upper enclosure is filled during the pump cycle in which the lower enclosure is outputting liquid. The pump thus has a repeatable cycle, although the gas pressure in the lower enclosure remains constant and liquid is constantly output from the pump at a controlled pressure.

Patent CA-2394991-A1 (CA)
Inventor: TANNER DOUGLAS J
IPC: B60T13/68
Filed: 2000-12-26
Abstract: The system controls the position of a pneumatically operated valve (12) using an electrical control signal from a controller (26). A pilot circuit (22) of the system has multiple piezo valves (30, 32) that are subject to electrical signals from the controller to provide pneumatic output signals to a volume booster circuit (20) of the system. Relatively small volume pneumatic pilot signals from the piezo valves are used to determine the opened or closed state of higher volume valve assemblies of the booster circuit which connect or disconnect the actuator of the valve to be operated with a source of pressurized gas (24). Both the piezo valves and the booster valve assemblies are subjected to gas at the same operating pressure, but the surface area of the pistons (82) exposed to the piezo valves is substantially larger than the surface area of the pistons exposed to operating pressure such that the pnuematic signals shift the pistons even when pressure is the same on both sides thereof.
Patent CA-2399481-A1 (CA)
Title: Method of coating particles by vapor deposition
Inventor: CARRIL DANIEL
IPC: C23C16/44
Filed: 2002-08-22
Abstract: A new fluidized bed particle coating method is disclosed by the use of which coatings can be uniformly and conveniently deposited on the surfaces of fluidized particulate materials by vapor deposition processes at temperatures lower than those of the heated coating precursor transport lines. By this method, particle materials with relatively low surface temperatures may be brought into close proximity with a coating precursor containing gas stream characterized by a substantially higher gas volume temperature in such a way that the vaporized precursor molecules are caused to adsorb or condense on the relatively cold particle surfaces without also condensing on any other surface. Further, if the adsorbed precursor molecules are capable of reacting or polymerizing on the relatively cold particle surfaces, thus forming substantially continuous coatings on those surfaces, they may do so without also depositing such coatings on any other surfaces. Such coating deposition processes cannot be carried out using conventional fluidized bed deposition methods or equipment.
